Benign cutaneous plexiform hybrid tumor of perineurioma and cellular neurothekeoma arising from the nose

چکیده
Very recently, Requena et al. have demonstrated the detailed clinicopathological features of 9 cases of a benign cutaneous plexiform nerve sheath tumor with hybrid characteristics of perineurioma and cellular neurothekeoma, given the name as a benign cutaneous plexiform hybrid tumor of perineurioma and cellular neurothekeoma, all of which were peculiarly located on the lips. Herein we described the first case of that arising from the nose, but not the lip, representing a histological hybridoma of perineurioma and cellular neurothekeoma after thorough consideration especially with its immunohistochemical profile.

Benign Cutaneous Peripheral Nerve Sheath Tumor with Hybrid Features: Report of Two Cases with Schwannoma/Perineurioma and Schwannoma/Neurofibroma Components
Hybrid benign peripheral nerve sheath tumors are rare tumors exhibiting areas of more than one neural neoplasm such as schwannoma/neurofibroma, neurofibroma/perineurioma, or schwannoma/perineurioma. These tumors usually arise in the skin of the extremities and trunk, and less commonly affect extracutaneous sites. Here we report two cases of these tumors exhibiting hybrid features of schwannoma/...
متن کاملA Soft Tissue Perineurioma and a Hybrid Tumor of Perineurioma and Schwannoma
Perineuriomas are composed of differentiated perineurial cells. Perineuriomas have been recently recognized by the immunoreactivity for epithelial membrane antigen (EMA). Microscopically, perineuriomas show proliferation of spindle cells with wavy nuclei and delicate elongated bipolar cytoplasmic processes. The tumor cells are usually negative for the S-100 protein. Ultrastructurally, perineuri...
متن کاملEvidence that anterior episcleral nerve sheath tumors arise from the Axenfeld nerve loop.
Comment. Although perineurial cell proliferation may be suspected histologically with routine hematoxylineosin staining, a definite identification needs the demonstration of perineurial cell features using immunohistochemical studies. The morphologic criteria include spindle cells with curved or wavy thin nuclei and thin, elongated cytoplasmic processes, arranged in lamellae, and a storiform gr...

متن کاملp63 immunohistochemical staining is limited in soft tissue tumors.
p63 is a p53 homolog that is expressed in various normal epithelial tissues and epithelial malignancies. Its expression in mesenchymal lesions has not been examined in depth; therefore, we studied p63 expression by immunohistochemical analysis in 650 soft tissue tumors. We found that p63 expression is limited in soft tissue tumors. The majority of tumors studied were p63-, including all cases o...
